Iranian Musician Hamid Reza Taherzadeh, who played at the vigil, said: "The leaders of the Muslim communities should be very, very firm, and they should come out and strongly condemn and denounce these killings. This is against the principles of Islam. Islam is not a religion of killings; Islam is a religion of hope, help, peace and love.

"Terrorists have come to destroy this harmony among the Muslims and non-Muslims. And for every Muslim it is crucial to come forward and strongly condemn these."

The group held anti-Isis banners outside the venue, which was stormed during an Eagles of Death Metal concert. Islamic State say the attacks were in response to French bombing of their territory.

Dowlat Nowrouzi, of the National Council of Resistance of Iran (NCRI) in the UK, said: "They do not represent any Islam. They are the heart of evil. They are not Muslims, they are enemies of Islam and we as Muslims want to say, we are with the French people. We are with all the democratic values".

France has called for a global coalition to stop Isis since the Paris attacks, and has launched a number of operations both in the city, and in Syria.
